" '1 FIRE-EXTIQNGUISHIER.

Be a known that I, I'IARVEY ,w. MIX, a c1t1z en of the United States, residing at Seattle, 1n the county of King and Stateof W ashington, have inventedjcertain new and useful Imrovements in Fire Extinguishers, of

- which the following is a specification.

My invention; relatesto certain new and useful improvements in'fireextinguishers; andthe primary obj ectthereofis to-improve and simplify the same.

With this ob 'ect inview the inventioncon sists'of the parts, arrangement, and combination of parts referred to in the following description and succinctly: pointed out in the 7 ap I ended claims.

i n the accompanying drawingsgin which likenumerals-of reference indicate like parts throughout the several 'views', Figure 1 is a fragmentary view showing theu per portion of the tank in vertical section, t e bottle or vessel containing the-acid being stoppered. Fig-'2 is a similar view, the -bottle,however,

being tilted and unstoppered. Fig. 3 is a detail view in perspective of the bottle-holder,

and Fig. 4= is a detail fragmentary view showing more particularly the means for supporting the bottle-holder. i

Referring more specifically to the drawings, 1 indicates the tank; having the dis;

- charge-pipe 2 and provided in its top with a remova apparent in the following.

1e plug 3, which-is preferablythreaded, as shown. This plug is formed with an opening 4 and a seat 5, the, latter being formed in the inner face of the plug and ened by flexible connection 11, which is secured at one end to the top of the tank and is of such length as to limit the movement of the stopper to less than that l of the bottle.

Therefore said stopper willbe removed from the bottle when holder? is tilted. (See Fig.

The means for tilting holder ,7 consists of a slidable rod 12, which projects into the tank through the aperture in plug 3, and a link 13, whichis ivoted to the'lower end of said rod and to a ug 13, secured to thelow'er portion Of holder 7.

Rod lzismanually o erated, and by s'uit- I i 6'0 ous.and on this rod I mount apressurepart .14, which when said rod is elevated toI-the limitof its movement snugly fitsin seat'5 and preventsany escapement of the chem vicalsolution throughopening, 4. Pressure part ,14 after being seated will be held by pressure, .and therefore accidental returning" of'holder 7 will be prevented.

As heretofore stated, holder 7 loosely' receivesthe bottle. This is desired inprderto facilitate the insertion and removal of the bottlein position, andin order to prevent displacement of the bottle when the'holder is tilted I provide a yoke consistin of opposite ivoted or hinged members15, aving their ee endssecured together by a pin 16 and one of which is bifurcated, asshown, so as-to embrace the neck of vthe'bottle'.

i H 'lhe bottle,-as heretofore stated, is loosely received in theholder 7' to facilitate the insertion and removal of the bottle therefromv In order to'prevent displacement ofthe bottle when the holder is tilted,-a yoke is r0,- vided consisting of opposite hinged mem ers 15, having their free ends secured together placement of the hol er 7 from rods 9.

The disohar e pipe 2 is of novel construc tion, the same avin a branch pipe 2 ,whioh communicates with t e tank at a point adj a- I cent its upper end, and this branch ipeis provided with a valve 2. this branch pipe is to rovide a means'of egress for that gas whic will remain in the tank after the liquid has been discharged. Thus the im rovement is made more eifect. ive and all 0 the fire-extinguishin agent can be directed onto a fire before refi ling of the tank is necessitated.

In operation, therefore, valve 2" is referably opened before the bottle is tilte as shown in Fig. 2. the-bottle are discharged the gas generated ing which is smaller than the bore of pipe 2, and therefore the liquid passing through pipe 2 under greater pressure; but when all The ob ect of J Then when the contents of I 105 will first force the liquid through the main, i discharge-pipe 2, the gas being prevented r from passing through thebranch pipe by i reason of the valve therein having an open 85 by a in 16, one of said members being bifur- I cate as shown, so as to embrace the neck of the bottle. Pins 8. revent accidental disof the liquid has been discharged the as will obviously be permitted to pass t rough branch pipe 2 unresisted.

I reserve the right to make alterations in the details of construction and relative arrangement of parts as defined in the appended claims without departing from the spirit of my invention,

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

L In a fire-extinguisher, in combination with the tank, a bottle-holding means pivoted therein, means for tilting said first means, and means acted u on by pressure in said tank for holding sai first means tilted.

2. In a fire-extinguisher, in combination with the tank, a bottle-holder pivoted therein, a means projecting into the tank and connected to send bottle-holder for swin ing the same, and means movable with the lastnamed means for closing the opening in the tank through which it passes.

- 3. In a fire-extinguisher, in combination with a tank, a bottle-holder swingingly mounted therein, movable means projecting into the tank for swinging the bottle-holder, and a pressure part fixed to said means and being adapted to be held about the opening in the tank through which it projects by pressure in the tank.-

4. In a fire-extinguisher, in combination with a tank provided with an opening, a stopper removably held in the opening of said tank, said stopper being formed with an aperture and a seat encircling the same, a

bottle-holder swingingly mounted in said tank, means slidable through the a )erture in said stopper and being connecte to said bottle-holder for swinging the same, and a means connected to the first means and being adapted for engagement in the seat of said stopper.

5. In a fire-extinguisher, in combination with the tank, and the acid-holding means therein, a means on the exterior of the tank for permitting the egress of the liquid and gas therefrom, said last means communicating with the tank at its upper and lower portions.

6. In a fire-extinguisher, in combination with the tank, a bottle-holder therein, means for supporting said holder for swin ing movement, and means independent 0? said first means for swinging said holder, said last means consisting of a rod projectlng into the tank, and a flexible connection between said rod and the lower portion of the holder.

In testimony whereof I ailix my signature in presence of two witnesses.
